My radwagon motor tops out at 32kph, I can pedal it up to about 40kph. At 40kph I can stop in 3m on dry tarmac, about 6m in snow.

For comparison, the cars I’m forced to ride with have a 24m braking distance at 40kph, but let’s be honest, there’s usually doing over 50kph despite the limit, so it’s more like 38-55m
